Nanoindentation of nickel manganite ceramics obtained by complex polimerization method
Апстракт
Nickel manganite is very interesting NTC material due to its outstanding
properties and wide field of applications mainly in microelectronics and
optoelectronics and lately in the mobile phone industry. In this work, chemical
synthesis of this material was performed by complex polymerization method (CPM).
The presence of pure nickel manganite phase was confirmed by X-ray analysis. The
obtained fine nanoscaled powders were uniaxially pressed and sintered at different
temperatures: 1000 C -1200C for 2h. Microstructure development during sintering
was observed by scanning electron microscope (SEM). Indentation experiments
were carried out using a three sided pyramidal (Berkovich) diamond tip. Young’s
modulus of elasticity at various indentation depths and hardness of NTC ceramics
were calculated. It was found that the highest hardness and elastic modulus exhibit
the ceramics sintered at highest temperature.
